Itchy bumps on vagina...28 weeks..help!!

Okay so I'm doing this anonymously cause its embarrassing!! Also I want to know from you all if this is normal around 28 weeks or am I like the only one??

Im 28 weeks pregnant and for the past few weeks I've noticed itchy bumps where my pubic hair grows and they're closer to my vagina. I asked my boyfriend to look at them since I can't see them and he said they have whiteheads. Lately I have been sweating and discharging a lot down there and wearing panty liners cause it will literally look like I peed my panties if I dont wear one. I wonder if the sweat/excess discharge is causing the bumps. It's not painful, just itchy and a little sore from itching.

It's not an STD..I was checked when I first found out I was pregnant and I've been with the same guy for 7 years and he has only been with me so none of that nonsense please lol.
